I've tried to reproduce it on an SMP i686 with 1024MB RAM, but there was no OOM there. > And here's a patch for you to try. It fixes the problem on my test > machine..... Excellent! After one run with that patch, the machine does not go OOM any more when running du(1) over this XFS filesystem. I've run du(1) login with my oom-debug script to gather sysrq-w and slabinfo, see https://trent.utfs.org/p/bits/2.6.39-rc4/oom/trace/16-* for the details. I'll poke it a bit more over the day, but your patch (one line only! Wow!) seems to help. Thanks so much, Christian. -- BOFH excuse #160: non-redundant fan failure _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
